Generally,there are two possible ways of active vibration cancellation,the Inertial mass
shakers,attached at suitable points,cancel out the disturbing vibration by a force signal of
opposite phase.On the other hand,active engine mounts compensate the displacement
between engine mount and the car body.Hereby the car body is kept free from the vibration
forces emitted from the engine.With regard to the specifications of the AVC system the
suitable system configuration has to be chosen.In (Hartwig et al.,2000),(Karkosch &
Marienfeld,2010) the electrodynamic and the electromagnetic actuator principle and the
two system configurations are compared.Figure 2 shows the electrodynamic and
electromagnetic actuator principles.
An electromagnetic actuator has the benefit to an electrodynamic actuator in higher actuator
force at decreased magnet and design volume such as more cost efficient.On the other side,
the electrodynamic actuator principle has the advantage in a simple design of the iron core
and the absence of magnetic forces lateral to the deflection direction.A comparison between
an active absorber and an active hydromount configuration is shown in Figure 3.
一般来说,有两种主动减振的方式:惯性质量振荡器,装配在适当位置,通过反向传力信号消除扰动力;另一方面,主动的发动机悬挂也抵消了发动机悬挂与车体之间的位移(震动).这样,车体就能有效地消除发动震动所带来的影响.对于AVC系统参数,必须选择合适的系统配置.在(Hartwig et al.,2000),(Karkosch &Marienfeld,2010)中,对 电动致动器和电磁致动器的原理和两套系统的配置进行了比较.表2中显示了电动致动器和电磁致动器的原理.
与电动致动器相比,电磁致动器具备的优势之一是在降低的磁和设计量的情况下拥有更高的致动力,因此也就具备更大的成本优势.另一方面,电动致动器的原理也具备自身优势,铁芯设计简单,没有挠曲方向上的磁力横向现象.主动减震器和主动液压悬置装置配置参数见表3.
